2 Claims. (Cl. 94-4) This invention relates to the class of roads andpavements and more particularly to a novel highway construction.

The primary object of the present invention resides in the provision ofa highway construction having means to absorb shock from rolling loadsand impacts thereby affording a surface having considerable tendency toresist breaks or cracks.

A further object of the invention resides in the provision of a highwayconstruction having a surface formed of a material that will aidin-traction and which is -constructed in a manner so as to permit longlife, easy maintenance and efficient drainage.

An additional object of the invention resides in the provision of ahighway construction capable of being constructed entirely by modernhigh capacity machinery so as to eliminate most manual labor and inwhich large portions of the highway can be substantially prefabricated.

A yet further object of the invention resides in the provision of ahighway in which conduits are formed in the steel sections thereof forreception of electric cables, pipes and the like eliminating overheadand unsightly utility connections heretofore utilized.

Still further objects and features of this invention reside in theprovision of a highway construction which may be substantially corrosionresistant, capable of having a resilient top made in long rolls andapplied mechanically and which is comparatively inexpensive to constructthereby permitting wide utilization on the highways of the nation. Y

These, together with the various ancillary objects and features of theinvention which will become apparent as the following descriptionproceeds, are attained by this highway construction, preferredembodiments of which have been illustrated in the accompanying drawings,by way of example only, wherein:

Figure 1 is a transverse sectional view of one form of a highweyconstructed in accordance with the concepts of the present invention;

Figure 2 is a vertical sectional detail view as taken along the plane ofline 2 2 of Figure l; and

Figure 3 is a partial sectional detail view of the modiiied form of thehighway construction.

With continuing reference to the accompanying drawings wherein likereference numerals designate similar parts throughout the various views,reference numeral is used to generally designate one form of highwayconstructed in accordance with the concepts of the present invention.

This highway 10 includes a pair of curb walls 12 and 14 having footingportions 16 and 18 of enlarged constructions so as to form the curbwalls 12 and 14 in generally an inverted T-shape.

Supported by the footings 16 and 18 of the curb walls and extendingtherebetween is a drainage base 20 which may include drain tiles or thelike and which may be constructed out of cementitiously bonded stone orslag, or the like. Positioned on top of the drainage base 20 is a baseplate 22 formed of steel which may be coated both on the top and bottomsurfaces with a suitable asphalt emulsion or other corrosion inhibitingcoating.

Welded to the plate 22 and rising therefrom are a plurality of suitablyspaced channels such as are indicated at 24, 26 and 28. To the channels24, 26 and 28 and the other channels there is welded an upper plate 30,the channels holding the upper plate 30 in spaced relationship relativeto the lower plate 22. The channels 24, 26, 28 etc., as well as theupper plate 30 may be suitably coated with an asphalt solution or othercorrosion resistant coating. The plates 30 and 22 may be made integralin considerable lengths and the individual lengths of the plates may beconnected by suitable expansion joints or the like, not shown.

Positioned on the upper plate 30 is a strip 32 of suitable material,such as rubber, having cords 34 embedded therein for reinforcement. Thisstrip 32 may be bonded to the upper plate 30 in any convenient manner byan adhesive solution or the like or may be otherwise afiixed into place.The strip 32 extends between the curb walls 12 and 14 and the uppersurfaces 36 thereof lies ush with the upper surfaces 38 and 40 of thecurb walls 12 and 14.

It is to be recognized that between the various channels 24, 26, 28 etc.and the upper and lower plates 30 and 22, respectively, there are formedsuitable conduits for cables, telephone wires, electric wires, and thelike, as well as, water and gas pipes and such other utilities asdesired.

In Figure 3 there is shown a modified form of the invention in which thebase plate 50 rests on the drain base 52, the base plate 50 beingprovided with depressions as at 54 and 56 for reception of the channels58 and 60 which are welded thereto, the depressions 54 and 56 serving tointerlock the plate 50 with the base 52 and to interlock the IchannelsS8, 60,' etc. with the base plate 50. The channels 58, 60 etc. as wellas the base plate 50 may be suitably coated with a corrosion resistantcoating of any suitable material. Positioned on the channels 5S, 60 etc.is an upper plate 62 having upwardly offset portions 64 and 66 forreception of the channels 58 and 60. These upwardly oifset portionsserve to form alignment means for the plate 62 and further form aninterlock for the wearing strip 68 posivtioned thereon, the wearingstrip being otherwise similar in construction to the wearing strip 32when having cutout portions for reception of the upwardly offsetportions 64 and 66 as may be desired.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows: v

1. A highway construction comprising a pair of spaced elongated curbwalls, a drainage base extending between said curb walls, an imperforatemetallic base plate overlying and resting on said drainage base,metallic channel members welded to said base plate and rising therefromin spaced parallel relationship, an upper plate disposed on and weldedto said channel members, and a resilient wearing strip on said upperplate between said curb walls, said base plate having spaced depressionstherein projecting into and interlocking with said drainage base, saidtop plate having upwardly offset portions projecting into andinterlocking with said wearing strip, said depressions and olsetportions being in vertical registry and said 'channels being received inthe recesses formed by said depressions'and offset portions.

2. A highway construction comprising a pair of spaced elongated curbwalls, a drainage base extending between saidlcurb walls, an imperforatemetallic base plate overlying'and resting on said drainage base,metallic channel members Welded to said base plate and rising therefromin spaced parallel relationship, an vupper plate disposed on and weldedto said `channel members, and a resilient wearing strip on said upperplate between said curb walls, said base plate having spaced depressionstherein projecting into and interlocking with said drainage base,said'top -plate having upwardly oiset portions projecting into andinterlocking with said wearingstrip, said depressions and oiset portionsbeing in vertical registry and said channels being received in therecesses formed by said depressions and offset portions, the uppersurface of said wearing strip lying flush with said curb walls.
